Bladestorm is already close to Dragon Roar's damage in a completely single target fight, however the problem with Dragon Roar on paragons is that it will hit multiple targets. Dragon roar has a diminishing return mechanic where it does less damage to the main target the more mobs you hit, so the damage will be split and the damage you do on the relevant paragon will be really small and as you said yourself the damage on other targets can be ignored.
As far as i remember dragonroar does only 65% of it's damage if you hit 3 targets which probably will always be the case on that fight.
Bladestorm however doesnt have this mechanic and does the same damage to the relevant target as if it was a completly singletarget fight.
Sure some people use bladestorm for padding and wait for parasites to spawn for more bladestorm damage or something like that, but if you just use it on cooldown after you used collossus smash it should yield higher single target damage on that fight than dragon roar does.
